Matter vs Z-Wave Smart Locks: Which Should You Buy in 2026?
For a new lock, Matter lets one lock join Apple Home, Google Home, Alexa and SmartThings at once, and a Matter over Thread lock suits batteries better than a Wi-Fi one. Keep a Z-Wave lock that works on your Z-Wave hub: certified Z-Wave products work across brands, and a bridge can bring Z-Wave devices into Matter later.

Fast Recommendation
For most new buyers, start with a CSA-certified Matter lock that uses Thread, and check that you have a Thread border router: Apple names Apple TV 4K, HomePod (2nd generation) and HomePod mini; Google lists the Google Home Speaker (2026), Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro and Google TV Streamer (4K) as hubs for Matter over Thread; SmartThings names its latest SmartThings Hub and SmartThings Station. Z-Wave suits homes that already run a Z-Wave hub.

Home Assistant and Matter lock codes
Home Assistant’s Matter integration documents actions to create or update a user on a Matter lock and to add or update a credential, such as a PIN. What each lock exposes over Matter depends on the lock, so check your exact model before replacing a Z-Wave lock whose codes and automations work today.

Matter Locks Worth Comparing First
Yale Smart Lock with Matter
Best mainstream deadbolt: Matter over Thread is built in, so no add-on module is needed. Yale designs it for Google Home and sells it on its own US store; Matter setup needs a Thread border router.
Aqara Smart Lock U100
Pick it when fingerprint unlock and Apple Home Key support matter most. The lock itself uses Zigbee and Bluetooth and reaches Matter through a supported Aqara hub.
Level Lock (Matter)
Best discreet lock if you want Matter over Thread in a replacement deadbolt that Level builds to sit inside the door.
FAQ
Is Matter better than Z-Wave for smart locks in 2026?
